Be it known that we, JOHN. Morn and CHRISTIAN F. Hem, citizens of the United States,- both residing at Cleveland, in the county of Cuyahoga and State of Qhio, have invented-a new and useful Wire less Transmitting System, of which the following is a' speclfication.

Gur invention relates to systems for developing and. transmitting electro-magnetic waves" a The object of our invention is a novel circuit arrangement whereby more powerful electro-ma 'etic waves can be developed and transmitted, and whereby the efficiency- 1 of such elective-magnetic wave development and transmission is increased.-

We attain our object by adding a pbwercircuit to'any wireless transmission apparatus or system. f Y

It is well known in the art that persistent oscillations and high power are the principal components to overcome long distance; the apparatus or system or the prior artpos sesses persistent oscillations, but sufiicient power to overcome long distance has not been obtained; we therefore, in this application, describe and show a new and novel circuit arrangement, in which a'power-source is c0- 30 cuit and with the'radiator-circuit; said osoperatively connected with the\oscillator-circilla'toncircuit, as heretofore employed, furnished the oscillations as well asfthe power, and, inasmuch as the methods and apparatuses employed to produce said oscillations will not permit: of high power, long distance transmission, as "for instance, in telephony,

has not been accomplished; we therefore 'employ said oscillator-circuit for the urpose of producing oscillations only, an 00- operatively connect a power source with isaidpscillator-circuit and with saidmadiatorcircuit; it will be seen that, by this arrangement, said power-source does not operate the oscillation apparatus "with its full energy or power, and therefore is not limited thereby, and that any amount of powermay be supplied to the system without regard toth'e oscillation apparatus.

aving' principles upon which our improvement de priora-rt, we shall now particularly describe pends and the advantage we have over the thus set forth general the two simple embodiments thereof which we have shown diagrammatically in the drawings for the purpose of- I'nore fully disclosing our invention ,but it is to be understood that such diagrams show only two of the nu- In the drawings: Flgure I represents the loop antenna, and Fig; 11 represents the circuit arrangement in connection with a linear antenna.- t

1 is the ower-circuit, 2 is the oscillatorcircnit,'an 3 and 3 are the antennae; in powercircuit 1 is inserted a source of power 'whi'ch niay' be a battery, a direct or alternating current generator, or any other source 'of power, which may be required and which source of power is preferably constructed and arranged so that it may be regulated ,or adjustedto, suit the distance to be overcome with such construction and arrangement the efiiciency of the system is increased inasmuch asonly the'necessary amount of power to overcome a desired distance needs to be used and further, such construction and arrangement is 'very useful and advantageous, particularly when used in connection with a wave-deflector, in sending electromerous possible embodiments of our inven-- circuit; arrangement in connection with a magnetic waves to a desired station; in

instance a or an oil blow-out, or a gas blow-out, and a variable inductance 9 which is for the purpose of preventing the energy from 08011- lator-circuit 2 from passing'through source of power i, and which maybe placed as shown in Fig. II or which maybe placed in primary 5 as shown in"Fig. I.

In oscillator-circuit 2 we show a plain circle which represents an apparatus for producing oscillations; said apparatus may rc method, or a Tesla'transbe the singing a I vformer,- or any other method of'producmg oscillations.

Antenna may be a loop antenna as'shown in Fig. I, or an open end antenna as shown in Fig. II, with or without a round wire, or may be any other kind of antenna.

The secondary 10 of transformer A is inserted into radiator-circuit.

Oscillator-circuit 2 may be supplied withpower from powersource 4 by means of a shunt as shown in .Fig. II, or -from a separate source of power, not shown in the drawin S. 4

lhe operation of this system is as follows: The oscillator-circuit 2, when in operation, will develop oscillations which will cause a succession of sparks to jump across air-gap (3, the'energy from power-source 4 will follow such sparks, thus opening and closing power-circuit 1, and will act through primary 5; such action will be impressed upon secondary 10 and upon the antenna; it is well known in the art that a current will follow a path made by another current however small: thus it will be seen that in our system the oscillator-circuit develops the oscillations and the power-circuit develops the power, and that our arrangement can be applied to any wireless system by the addition of our power-circuit; with'this sy tem we can develop and transmit electroma netic waves of any shape, either long or short, regular or irregular, of any frequency, persistent or otherwise, and of any power desired, such desire being limited only by power-source; the systems of the prior art employ no power-circuit as we do, but depend upon the charge and discharge of condensers, and for that reason long distance transmission, for instance in telephony, was

not a success.

. Among the advantages of this invention may be mentioned that, inasmuch as we employ a power-circuit, we are able to develop and transmit more powerful electro-mag netic waves, thus overcoming longer dis tance, and doing so more efliciently.

This invention can be used in wireless telegraphy, wireless telephony, -wireless power transmission, X ray, and other processes which are dependent for their opera- -tion upon disturbances in the ether.

\Vhile We have shown our invention embodied in certain apparatus, it is not to beinferred that such apparatus represents the only forms in which our invention may be embodied, but are illustrated and described only as illustrative of arrangement, to make clear the principle of application of our in-,

vention.

We have nothing new in either oscillator or antenna, and do not particularly claim power conductively connected to the oscillator-circuit and inductively connected with the radiator-circuit.

A system of wireless transmission of electro-magnetic waves consisting of a power-circuit into which is inserted a source of power, an air-gap and the primary of a transformer, of an oscillator-circuit which opens and closes said power-circuit at said airgap and which may be supplied with energy from any source of power, and of a radiator-circuit into which is inserted the secondary of said transformer.

4. In a system 'of wireless transmission of electromagnetic waves the combination 'of a power-circuit into which is inserted a source of power, an air-gap and the primary of a transformer, of an oscillator-circuit which opens and closes said power-circuit at said air-gap, 'of a radiator-circuit into which is inserted the secondary of said transformer, and of a blow-out at said airgap.

5. In a system of wireless transmission of electro-magnetic waves the combination of a power-circuit into which is inserted a source of power, an air-gap and the primary of a transformer, of an oscillator-circuit which opens and closes said power-circuit at said air-gap, of a rad1ator-c1rcu1t into which is inserted the secondary of said transformer, 'of a blow-out at said air-gap, and' of a variable inductance in said power-circuit.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses;
